Please read this installation manual completely before installing the short shifter. Make sure to let the car cool down before you do the install as you will be working on and around the exhaust line. This manual is available for download in color at www.twmperformance.com.

1. Working in the engine bay, start removal of the stock air box by removing the bolt on the top part of the air box as pictured to the left. Use a 10 mm socket and a ratchet. Put it aside for re-install later. If you have an aftermarket intake, proceed to step #10 for battery removal. 2. Unclip the two (2) clips holding the top part of the air box as pictured to the left. 3. Unplug the MAF connector as pictured to the left.
4. Unclip the rubber hose over the intake as pictured. 5. Loosen the bolt holding the intake piping to the throttle body using a 10mm socket and a ratchet. 6. You can now remove the air box top half from the throttle body.
7. Pull on the hose on the top of the intake to remove it as pictured. 8. Working at the rear of the air box, you will see the MAF wiring is held on the box itself with a tab. Use needle nose pliers to squeeze the tab and push it out. 9. Pull up on the air box to remove it from the engine bay. Take good note of both rubber grommets where it s installed in as it will need to be reinstalled the same way. Put it aside for re-install later.
10. Pull on both tabs holding the top part of the battery box and remove it. This top part has 2 tabs at the back that are inserted in two slots on the bottom part. To remove it, lift the front part up and then slide it toward the front of the car. Put it aside for reinstall later. 11. Using a 10 mm socket and ratchet, unbolt the battery holder. There is a bolt on each side of the battery. Put it aside for re-install later. 12. Unbolt both battery terminals using a 10 mm socket with a ratchet. Remove the battery from the engine bay and put it aside for re-install later.
13. Using a 12 mm socket and a ratchet, remove the three (3) bolts at the bottom holding the battery box in place. Put them aside for re-install later. 14. The two (2) grey tabs behind the battery connector on the front part of the battery box needs to be pushed out. Use needle nose pliers to squeeze them and push them out. 15. You can now remove the front part of the battery box as pictured. Put it aside for re-install later.
16. Using needle nose pliers, squeeze the plastic tab holding the wiring harness to the bottom of the battery box and push it out as pictured. 18. Repeat the same for the tab pictured to the left. 19. Tilt the battery box toward the front of the car where the air box was.
20. You now have access to the shifter cable and shifter actuator where the short shifter will be installed. Use a long flat head screwdriver to pop the left cable out of the shifter arm. Do not apply too much force, it will come out easily. This is easier done when the shifter is in lower gears (2 nd, 4 th, 6 th or R). 21. Install the aluminum part of the short shifter under the shifter arm as pictured to the left. It can only be installed one way. 22. Put a drop of the provided blue loctite on the three (3) allen bolts provided in the kit. Install the provided washers on the bolts, one washer per bolt.
23. Install the top plate of the short shifter as pictured to the right. Tighten all three allen bolts in sequence until they are fully tight with a 5mm allen wrench. Make sure the gap between the aluminum plate and the adapter plate is even all around, re-adjust it if necessary. Attach the shifter cable on the TWM pivot arm. Push on the cable until it s correctly clipped on. Re-install everything by reverting steps 1 to 19.
